Today is Children's Day. Some children ask you to output a big letter 'N'. 'N' is constituted by two vertical linesand one diagonal. Each pixel of this letter is a character orderly. No tail blank is allowed.
For example, this is a big 'N' start with 'a' and it's size is 3.

a e
bdf
c g

Your task is to write different 'N' from size 3 to size 10. The pixel character used is from 'a' to 'z' continuously and periodic('a' is reused after 'z').

This problem has no input.

Output different 'N' from size 3 to size 10. There is no blank line among output.

[pre]
a e
bdf
c g
h  n
i mo
jl p
k  q
.........
r        j
[/pre]

Hint
Not all the resultsare listed in the sample. There are just some lines. The ellipsis expresseswhat you should write.
 

把一道模拟题做成这样，我也是醉了，这个还是最早看过一个ACMer的博客，才这样写的。。。

# include<cstdio>
# include<iostream>
# include<cstring>
using namespace std;

int main(void)
{
    printf("a e\nbdf\nc g\n");
    printf("h  n\ni mo\njl p\nk  q\n");
    printf("r   z\ns  ya\nt x b\nuw  c\nv   d\n");
    printf("e    o\nf   np\ng  m q\nh l  r\nik   s\nj    t\n");
    printf("u     g\nv    fh\nw   e i\nx  d  j\ny c   k\nzb    l\na     m\n");

    return 0;
